Resistance 0.47 ohm 1/2W tolerance ±5% flame retardant
Metal Film Resistors are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal alloys and passivated materials onto a carefully treated high quality ceramic substrate. After cutting a helical groove in the resistive layer, the tinned connection conductors of electrolytic copper are soldered to the end caps. The resistors are coated with layers of paint of various colors on which the colored bands that indicate the value are impressed. Each of the colored bands has a specific meaning. The first two colors provide the base value of the resistance, the next one provides the multiplier and the final band the tolerance. If a resistance has five bands, it is a more precise resistance, in which the first three bands represent the base values and the fourth and fifth represent the multiplier and the tolerance respectively.
